Mars and its satellites. Drawings, interior of the planets

This drawing of the planet Mars and its satellites, by Calvin J. Hamilton, shows the red planet with its two satellites, Phobos in the foreground and Deimos in the background, on the right. Both are dark bodies that appear to be composed on the surface by blackish carbonaceous chondrites such as those that exist in the outer asteroid belt.

Some scientists speculate that they could be asteroids captured by the force of gravity from Mars.

Phobos is the innermost satellite, at a distance of 9.378 km. It is the one that is closest to your planet of all the satellites of the Solar System. Deimos has its orbit 23,460 km from Mars. It is blackish and similar in nature to many asteroids.

Phobos measures about 21 km in diameter and Deimos only about 12 kilometers
